Green Lodge is a minimalist subterranean residence located in Putney Heath, London, United Kingdom, designed by Stylus Architects. The brief was simple to the point of provocation: a longstanding contractor client told the studio to do whatever it wanted, provided the build moved fast, and the result is a house that answers a sensitive, tightly bound site by declining to compete with it. Rather than asserting height or footprint against the Gothic Revival church to the south, the Victorian villas, and the Arts and Crafts houses nearby, the architects drew the house into the ground, leaving only a modest presence above grade while excavating a full family home below.
That below-ground strategy is as much a planning tactic as a spatial one. Reducing the building’s visible mass was the mechanism for unlocking generous accommodation on a constrained plot, and the architects used the resulting compression to sharpen the house’s internal logic. Two fair-faced concrete spine walls run from foundation to roofline, splitting the plan into three bays and appearing, unclad, in every room. The decision to expose rather than finish the concrete gives the house a materials palette that reads as structural honesty rather than decoration, a strategy with roots in postwar brutalist domestic work but deployed here at a much more intimate, residential scale.
Larch does the opposite work above ground. Cladding the entire volume, including the roof, the timber unifies the exterior into a single sculptural mass that will silver with weathering, gradually receding into the wooded heath setting it already imitates in form. The vaulted roof’s asymmetry is not incidental. Its geometry, along with the plan’s bay divisions and the exact placement of the kitchen island beneath the central rooflight, follows golden ratio proportioning, a classical device repurposed here to organize a resolutely contemporary section.
Daylighting becomes the project’s real technical achievement, since most of the house sits below the heath’s surface. A large rooflight over the staircase pulls light down through every level to the basement hall, while south-facing lightwells reach each subterranean bedroom, pairing them with private external terraces so that below-grade living does not mean below-grade daylight. At night, artificial lighting is calibrated to the same geometric logic as the architecture, aligned rather than layered on. The staircase, lit from above, becomes the house’s vertical spine both structurally and experientially, while the kitchen island’s bespoke lighting bar continues the golden ratio alignment established in the roof.
